Outdoor illumination synchronous signal system based on NFDM PLC technology

The utility model belongs to the technical field of outdoor lighting systems, and particularly relates to an outdoor lighting synchronous signal system based on the NFDM PLC technology, which solves the problems that an NFDM system is difficult to be combined into a lighting synchronous system and the reliability of communication signals is poor, and comprises a large lighting system which is electrically connected with a plurality of synchronous receiving systems, the plurality of synchronous receiving systems are jointly and electrically connected with a synchronous sending center system, and the synchronous sending center system sends a synchronous signal to each synchronous receiving system to receive the synchronous signal and then transmits the synchronous signal to the large-scale lighting system; the large lighting system comprises a lighting unit I, a lighting unit II and a lighting unit N. Through the arrangement of structures such as a synchronous sending center system and a synchronous receiving s
